How do you adjust tailgate latch on 1988 Sierra?

To adjust the tailgate latch on a 1988 GMC Sierra, first, open the tailgate fully. Inspect the latch mechanism for any wear or misalignment. If necessary, loosen the bolts securing the latch to the tailgate, then reposition it to ensure proper engagement with the tailgate's catch. Tighten the bolts back in place and test the latch to ensure it closes securely.
